Kind: research · Impact: low

## In brief

- Scientists report that a 24-hour fast increases a beneficial gut bacterium.
- The bacterium helps the intestines regenerate after radiation damage.
- The findings are preclinical, so they are not yet tested in human treatment.

## Why it matters

The work points to a possible way to protect healthy intestinal tissue during cancer radiotherapy, though it remains at an early research stage.
